Carnegie Mellon University's 2010 Dickson Prize awardee is chemist and materials scientist Dr. David A. Tirrell, who is world-renowned for his innovative discoveries in polymer chemistry and macromolecular engineering. In his early research, Tirrell made important macromolecular discoveries that have made the development of "smart" materials -- those that respond to external cues like light, pH or temperature -- possible. Most recently, an...more
Note: The Strange Case of the Erotic Kiss is at 56:30 This lecture is the last hour of the last lecture of COMP1917 - the higher stream of the first computing course of the School of Computer Science and Engineering at UNSW. We discussed the structure of the final exam. (Richard has some crazy ways of structuring exams - before the exam make sure you read the sample exam on the course homepage if you missed this lecture - so you don't ge...more
Early Modern England: Politics, Religion, and Society under the Tudors and Stuarts (HIST 251)Professor Wrightson begins by assessing the state of education in the late medieval period and then discusses the two cultural forces (Renaissance humanism and the Reformation) which lay behind the educational expansion of the sixteenth and seventeenth centuries. While there were distinct hierarchies of learning in the period (with women and the lo...more
Capitalism: Success, Crisis and Reform (PLSC 270) A practical theory of freedom is discussed, based on Hayek's Constitution of Liberty. Free societies can be thought of as great learning machines capable of aggregating individuals' knowledge and accomplishments. Professor Rae uses examples from automotives and university administration to illustrate how freedom allows everybody to profit from others' knowledge. Professor Rae also highligh...more
Professor Summers, former U. S. Treasury Secretary and former President of Harvard University, in this the first of two lectures in honor of former Yale Professor and Council of Economic Advisors chairman Arthur Okun, offers thoughts on the role of monetary policy in economic fluctuations, past and present. In the "Okun period," ending about when Okun died in 1980, the monetary authorities were very much involved in actually creating econo...more
In this lecture, Professor Freedman considers the importance of the British Isles in the early Middle Ages, both in their own right and as an example of a post-Roman frontier society. In the wake of the fifth century Roman withdrawal, England experienced "radical economic simplification." However, England's conversion to Christianity beginning at the end of the sixth century brought about a flourishing written culture and Latin learning. I...more
Companies today need to be nimble and adaptable to the changing environment and market around them. Being nimble is important. The second skill is to think through when you're going to ship your product. If you think about the innovation; is it a 2x improvement, is it a 10x improvement? Think about what the market will be when you ship your product. If you have a four-year development cycle, youwill have a physical product that's going to ...more

This beautifully illustrated lecture explores the connections and interactions between British writers and artists. As children, learning to read, we look first at the pictures in books - they tell the tale in their own way. With great writers, this power endures: artists connect with words in different ways. This lecture will explore fascinating examples of the relationships between artists and writers, from those that work independen...more
Class begins with a problem on transits and learning what information astronomers obtain through observing them. For example, radii of stars can be estimated. Furthermore, applying the Doppler shift method, one can find the mass of a star. Finally, a star's density can be calculated. A second method for identifying planets around stars is introduced: the astrometry method. The method allows for an extremely accurate assessment of a star's ...more

We start by discussing the skater guy from last lecture. intrinsic vs extrinsic motivation. deep and surface learning. class reps revisited briefly. what can go wrong. what courses of action are open to you to deal with things going wrong in your code? we look at 4 general strategies and discuss their relative strengths and weaknesses. assert as a way of documenting assumptions and of checking them. contracts. who is to blame. what can y...more
